MTM Rifle Slip Top 20-Round Ammo Case for 7mm Rem-338 Win Mag - Red

The MTM Rifle Slip Top 20-Round Ammo Case for 7mm Rem-338 Win Mag is purpose-built storage for centerfire rifle ammunition in larger magnum calibers. If you're stocking 7mm Remington Magnum or .338 Winchester Magnum rounds—whether you're loading for long-range hunting, precision rifle matches, or building a serious ammo supply—this rigid plastic case keeps your ammunition organized, protected, and ready to grab. The slip-top design means you can access your rounds quickly without fumbling with latches, and the compact footprint fits easily in a range bag, truck cab, or reloading bench.

MTM's polypropylene construction has earned trust among serious rifle shooters and reloaders worldwide. The material resists warping, cracking, chipping, and peeling over years of use—no brittleness in cold weather, no deformation from stacking or pressure. The case holds 20 rounds in a bullet-up orientation, which keeps your ammunition visible and ready to load. Many reloaders appreciate the open-top design because it prevents the lid from contacting bullet tips, an important detail if you're running custom loads with extended seating or match-grade bullets.

This is genuine MTM quality in a straightforward, no-frills package. You get durable storage sized for magnum rifle cartridges, and that's exactly what you need when you're serious about your ammo.
